the scale of 1/250,000 of the same stand- 
ard of accuracy as the work of the United 
States Geological Survey on maps of this 
scale. In the Valley of Ten Thousand Smokes, 
beside continuation of the general exploration 
and securing many valuable photographs, they 
succeeded in obtaining the first accurate meas- 
urement of the temperatures of the vents. For 
this purpose the expedition was equipped with 
pyrometers by the geophysical laboratory of 
the Carnegie Institution. They report the 
highest temperature measured as 430° C. Al- 
though this is subject to correction when the 
instruments are recalibrated on returning to 
the states, it probably indicates correctly the 
order of magnitude of the temperature of the 
valley. The expedition expects to return home 
overland via the Iliamna route, probably reach- 
ing Seattle about September 15. 
A WasuincTon Section of the American In-

Tue Committee on Mineral Imports and 
Exports has finished its work of formulating 
programs for the minimum importation of ores 
and minerals, and the members of the com- 
mittee have taken up other work. Professor 
C. K. Leith has been appointed mineral ad- 
viser to the War Industries board from the 
standpoint of the conservation of shipping, 
Mr. J. E. Spurr is in charge of the war min- 
erals investigation work of the Bureau of 
Mines, and Mr. Pope Yeatman continues in 
charge of the Non-Ferrous Metals Divisions 
of the War Industries Board. 
We learn from Nature that the Electrical 
Research Committee, which was appointed last 
autumn, under the auspices of the Depart- 
ment of Scientific and Industrial Research, is 
at present engaged in superintending a re- 
search on insulating materials (fibrous mate- 
rials, porcelain, ebonite, mica, composite mate- 
rials) and the water-proofing treatment of 
insulating windings of electrical machines, in

respect of which grants have been made to 
the Committee by the Research Department, 
the British Electrical and Allied Manufac- 
turers’ Association, and the Institution of 
Electrical Engineers. The Committee con- 
sists of three members nominated by the in- 
stitution, and three members nominated by 
the B.E.A.M.A., the nominees of the former 
being Mr. C. H. Wordingham (chairman of 
the Committee), Mr. C. C. Paterson, and Mr. 
C. P. Sparks, and those of the latter Mr. F. R. 
Davenport, Mr. D. N. Dunlop, and Mr. A. R.

THE Journal of the American Medical Asso- 
ciation states that the members of the Na- 
tional Public Health Service of Brazil have 
erected a monument to Oswaldo Cruz on the 
grounds of the Public Health Building at Rio 
de Janeiro. The bronze portrait figure is 
seated in the professorial chair, with arms 
_ testing on a desk, in a peculiarly graceful and 
easy pose. The inscription reads: “A Os- 
waldo Cruz, Homenagem do pessoal da Direc- 
toria Geral de Saude Publica, 23-ITI-1903— 
19-VIII-1909,” the dates marking the period 
of his most productive work, the eradication 
of yellow fever from Rio. The statue was un- 
veiled with much ceremony recently in the 
presence of the highest officials of the country. 
The Brazil Medico of June 15 gives an illus- 
tration of the memorial. 
Harry Kirke Wotre, professor of philos-

Tue death is announced of G. Verriest,
